Because they are used to improve elements of host resistance that are known to be important in periodontal health and disease, three naturopathic medicines are potential adjuncts in preventing and treating periodontitis. Connective tissue components are enzymatically degraded in periodontitis. In naturopathy, Connective Tissue Nutrient Formula (CTNF) (vitamins A, C and D, glucosamine sulfate, oligoproanthocyanindins, copper, zinc, manganese, boron, silicon, magnesium, and calcium) is prescribed specifically to enhance the integrity of key connective tissue elements and improve their resistance to degradation. Periodontitis begins when permeability of the oral sulcular epithelium permits pathogenic bacterial components to invade deeper periodontal connective tissues. In naturopathy, glutamine is prescribed to reduce oral-intestinal epithelial membrane permeability. Chronic activation of the hypothalamic-pituitary-adrenal (HPA) axis during the stress response, is a risk factor for periodontitis. Adaptogenic herbs (AH) (Panax ginseng, Withania somnifera and Eleutherococcus senticosus) are prescribed by naturopathic physicians to reverse the impact of bacterial and psychosocial stressors. Because glutamine, CTNF and AH target pathophysiologic mechanisms known to underline periodontitis, they are compelling candidates in clinical and mechanistic investigations of complementary medicine approaches to the management of periodontitis.
